There's no definitive answer to this question since salaries can vary depending on a number of factors, including experience, location, and company size. However, in general, sales engineers tend to earn more than product managers.
Sales engineers typically have a background in engineering and are responsible for Technical Pre-Sales support. This means they work with potential customers to provide them with the technical information and expertise they need to make a purchase decision. Because of their technical expertise, sales engineers typically earn higher salaries than product managers.
Product managers, on the other hand, are responsible for managing the development and rollout of products. They work with cross-functional teams to ensure that products are designed, developed, and delivered on time and on budget. Product managers typically have a background in business or marketing, and while they may have some technical knowledge, they don't usually have the same level of expertise as sales engineers.
So, in general, sales engineers tend to earn more than product managers. However, there are many factors that can affect salaries, so it's difficult to say definitively.
